Therefore, the terms used herein must be defined based on the meaning of the terms together with the description in the entire specification. In addition, when a component "includes" or "contains" an element, unless there is a specific description to the contrary, the component may also include other elements without excluding other elements. In the following description, terms such as "component" and "module" indicate a unit for processing at least one function or operation, wherein the unit and module can be implemented as hardware or software or by combining hardware and software and implemented.

[0020] Embodiments will now be described more fully with reference to the accompanying drawings. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the embodiments to those of ordinary skill in the art. In the following description, well-known functions or structures are not described in detail because they will obscure the embodiments with unnecessary details, and throughout the specification, the same reference numerals in the drawings represent the same or similar elements.

[0021] Attached Figure 1 is a perspective view of the locking device of the present invention according to the present invention, Figure 2 The locking device in this embodiment is used to lock the solid state drive 10 on the circuit board, and the locking device can be used in various electronic devices, including laptop computers, desktop computers, all-in-one computers, tablet computers, and mobile phones.

[0022] The locking device includes a structural body 1, a lock tongue 2 is arranged on the structural body 1 in a transversely retractable manner, a spring 3 is arranged inside the structural body 1, the spring 3 is elastically supported between the structural body 1 and the lock tongue 2, and also includes an unlocking component for driving the lock tongue 2 to extend or retract in the transverse direction to lock the solid state drive 10 between the circuit board and the lock tongue 2.

[0023] In this embodiment, the unlocking component includes a first pressure block 4 and a second pressure block 5 which are longitudinally retractable and arranged on the structural body 1. The upper side of the lock tongue 2 has a first driving part 6 and the lower side has a second driving part 7. The first pressure block 4 is located above the lock tongue 2, and the lower end of the first pressure block 4 abuts against the first driving part 6. The second pressure block 5 is located below the lock tongue 2, and the upper end of the second driving part 7 abuts against the second driving part 7. When the first pressure block 4 and the second pressure block 5 are pressed, the lock tongue 2 retracts in the horizontal direction. When the first pressure block 4 and the second pressure block 5 are released, the lock tongue 2 elastically extends in the horizontal direction. The moving directions of the first pressure block 4, the second pressure block 5 and the lock tongue 2 are perpendicular to each other.

[0024] A third driving portion 8 is provided above the lock tongue 2. When the solid state hard disk 10 presses the third driving portion 8 downward, the lock tongue 2 retracts laterally. A limiting portion 9 is provided above the lock tongue 2. When the lock tongue 2 retracts laterally, the limiting portion 9 blocks the structural body 1.

[0025] In other embodiments of the present invention, the unlocking component may also be a rotating structure or a sliding structure.

[0026] Attached Figure 3 To Attachment Figure 5FIG. 1 is a working principle diagram of the locking device according to the present invention. In this embodiment, the structural body 1 is mounted on a circuit board through an SMT process, so a connector 11 is disposed on one side of the circuit board and a locking device is disposed on the other side.

[0027] During the installation process, the connection end of the solid state drive is inserted into the connector 11, and the other end is pressed downward with force. Since the third driving portion 8 includes an inclined surface, when the solid state drive 10 presses the third driving portion 8 downward, the lock tongue 2 is retracted laterally into the structural body 1; when the solid state drive is pressed down into place, the solid state drive and the lock tongue 2 are offset, the force on the third driving portion 8 disappears, and the lock tongue 2 is driven by the elastic force of the spring 3 to extend laterally from the structural body 1, thereby locking the solid state drive 10 between the circuit board and the lock tongue 2.

[0028] During the disassembly process, the first pressing block 4 and the second pressing block 5 are pressed, and the locking tongue 2 is retracted into the structural body 1 in the lateral direction to overcome the elastic force of the spring 3, one end of the solid state hard disk is taken out from under the locking tongue 2, and the connecting end of the solid state hard disk is moved out of the connector 11; the first pressing block 4 and the second pressing block 5 are released, and the locking tongue 2 is extended from the structural body 1 in the lateral direction driven by the elastic force of the spring 3.

[0029] The present invention utilizes a spring pressure rod structure to lock the solid state hard disk, which can avoid the risk of damage caused by assembly and save assembly time.

[0030] It should be understood that the embodiments described herein should be considered in a descriptive sense only and not for the purpose of limitation. The description of the features or aspects within each implementation side should generally be considered to be applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope defined by the appended claims.
